Design of Lower Conservatism Robust Controller for Interval Matrix Systems
区间矩阵系统低保守性鲁棒控制器的设计

In this paper, a method of determining the minimum upper bound and maximum lower bound of the real symmetric matrix set is proposed and applied to design the robust controller for the uncertain systems with system matrix and input matrix being interval. Thus the complex problem of determining the solution of matrix inequalities is simplified to that of solving single algebraic Riccati equation.The method is of lower conservatism.
